方便乌鳢鱼头汤喷雾干燥工艺优化及品质评价

Study on optimization parameters of spray drying and quality evaluation of Channa argus head soup drying product

  • 摘要: 为满足消费者对美味鱼汤产品的需求,提高乌鳢 (Channa argus) 加工副产物的利用价值,以前期制备的乌鳢鱼头汤为原料,用麦芽糊精作助干剂,采用喷雾干燥法制备乌鳢鱼头汤粉末,以干燥粉末的水分质量分数、色泽、溶解性、堆积密度、冲调时间以及粘壁情况为评价指标对喷雾干燥工艺优化进行研究。结果表明,麦芽糊精能够有效提高喷雾干燥的集粉率、粉体亮度、溶解性,改善粘壁情况;麦芽糊精质量浓度为15 g·L 1、喷雾干燥进风温度为170 ℃、进料速度为6 mL·min 1时喷雾效果和产品品质最佳,所制得的乌鳢鱼头汤粉末具有含水量较低、堆积密度较大、溶解度较高、吸湿性较低和颗粒均匀等特性。综上,喷雾干燥法可作为乌鳢鱼头汤粉末的制备方法。

     

    Abstract: In order to meet consumers' demand for delicious fish soup products, and improve the utilization value of Channa argus processing by-products, we prepared the fish head soup by spray drying method using C. argus head soup as raw material and maltodextrin as a drying aid. The optimization of spray drying technology was carried out by analyzing the water mass fraction, color, solubility, bulk density, time of punching and viscosity of dry powder. The results show that maltodextrin could increase the spray drying rate, powder brightness and solubility effectively, and improve the adhesive condition. With the maltodextrin addition amount of 15 g·L 1, spray drying inlet temperature of 170 ℃ and feeding speed of 6 mL·min 1, the spray effect and product quality were the best. The prepared fish head soup powder contained low water content, large packing density, high solubility, low moisture absorption and uniform particle size. In conclusion, spray drying method can be used as a preparation method for fish head soup.
